6 Claims.

My invention relates to mechanism for attaching a plurality of webs together while maintained in face-to-face relation.

In accordance with my invention, a plurality of face-to-face webs are moved along a path and, preferably by mechanism automatically operable, said webs are secured or attached together so that one web forms a backing for the other Web.

Further, my invention relates to novel mechanism for attaching an opaque backing to a transparent or translucent web so that characters printed on the last named web may readily be distinguished.

Further objects, advantages and features of my invention will become apparent from the following description.

My invention resides in the novel mechanism, features and combinations of the character hereafter described and claimed.

For an understanding of my invention and for an illustration of some of the many forms thereof, reference is to be had to the accompanying drawings, in which:

Referring to Fig. 1, I have illustrated a combined printer-projecting system which may be of any suitable character as well known in the art. For purposes of explanation of the invention, the printer-projecting system herein illustrated is of the character disclosed in Weller application Serial No. 636,490, filed October 6, 1932, which has become Patent No. 2,128,867, dated August 30, 1938. As herein generally shown, although not necessarily, the printer P is of the character known to, the art as at Dow- Jones printer and, hence, comprises a printing wheel I rotatable and movable longitudinally of a shaft 2, the printing wheel I receiving ink from a suitable inking arrangement 3. Coactable with the printing wheel I is a platen 4 pivoted on a rod 5 supported in the printer frame structure 6. The web W, of suitable transparent or semitransparent material, is stored in roll formation upon a suitable reel, not shown, said web W extending upwardly along a path between the platen 4 and the printing wheel I. As well understood in the art, a printer P of the type referred to comprises means automatically operable to feed the web W a line space at the conclusion of each line-printing operation. As the invention is herein shown, the web-feeding mechanism has not been illustrated but I have shown the terminal gear I of the train of gears which actuates said web-feeding mechanism.

As more particularly disclosed in the aforesaid Weller application Serial No. 636,490, filed October 6, 1932, the projector herein illustrated comprises a lamp housing 3 which, in: suitable manner,'supports a socket 9 for a lamp H), the projecting beam of light passing from right to left, Fig. 1, through a passage 8a formed in said lamp housing 8. As the projecting light beam passes in the direction just stated, it traverses a pair of condenser lenses ll supported in a housing i2 suitably secured to said lamp housing 8. At the side thereof removed from the lamp housing 8, the condenser housing I2 comprises a passage l2a. through which the projecting light beam passes and thereafter engages a mirror i3 by which said projecting light beam is directed vertically up so as to traverse an objective lens 14, the projecting light beam thereafter engaging a suitable mirror system, not shown, by which it is directed to the projection screen.

The mirror l3 and objective lens M are carried by a bracket l5 which is secured to a frame IS, the latter comprising members I6a which extend downwardly on the respective opposite sides of the projection field and, at their lower ends, carry a transverse member I! upon which a. plurality of spaced wheels l8 of knife-edge construction are mounted. Each of the wheels I8 is adapted to hold the adjacent section of the web W in engagement with a finger 19, all of these fingers being pivoted on a rod 20 carried by the condenser housing [2 and each finger being biased in a counter-clockwise direction, Fig. 1, under the influence of gravity.

Above the projection field, the condenser housing 12', at each side thereof, comprises an ear I2b which carries a horizontal shaft 2|] having secured thereto a plurality of feed rollers 2|, said shaft 20 being connected by a flexible shaft 22 to a gear wheel 23 mounted on a support secured to the printer P, said gear wheel 23 meshing with and being driven by the aforesaid gear wheel I.

The frame I6, at the respective opposite sides of the projection field |2a, comprises spaced lugs which support a rod 24 upon which a plurality of rollers 25 are mounted. As illustrated, the rollers 25 are loosely mounted on the rod 24- and, accordingly, they are biased in a downward direction by action of gravity.

As shown, the web W extends upwardly through the projection field and is disposed between the feed rollers 2| on the one hand and the rollers 25 on the other hand, the rollers last named holding the web in engagement with said feedrollers 2|.

In operation, the printer P is actuated under remote control to cause all or a part of a line of characters to be printed transversely on the web W. After completion of the printing of such line of characters, the operator, by a control suitably effected, causes the printing wheel to be returned to its initial position and, at this time, the gear wheel 7 hs a step of rotative movement imparted thereto whereby, under the control of the gear wheel 23 and shaft 22, the feed rollers 2| have imparted thereto a step of rotative movement in a clockwise direction, Fig. 1, whereby the web W is moved a corresponding line space through the projection field l2a.

Referring to Fig. 1, suitable stapling mechanism S is shown as supported in operative position in any siutable manner, as, for example, by one or more standards or members 30 secured to and upstanding from the aforesaid lamphousing 8. Carried by the standards 3|] are a pair of side plates 3| and 3|, Fig. 3, which are vertically secured in spaced relation by a plurality of tie rods 32, or equivalent.

Pivotally supported in any suitable manner, as by one of the tie rods 32, are a pair of spaced arms 33 secured together at their free ends by a transverse rod 3 Fig. 1, on which is supported a web-engaging roller structure 35 comprising, preferably, a plurality of knife-edged, freely rotatable disks 36.

Extending transversely between and suitably secured to the aforesaid side plates 3| is a plate 37 which, at its opposite sides, comprises the respective passages 31a. Disposed above each passage 3M and suitably secured to the plate 31 is an anvil 38. Disposed below each passage 31a is a hammer 39 of a suitable stapling unit 40 loosely supported on a pivot 4| carried by and projecting from the adjacent side wall 3|. Disposed in vertical alinement with each passage 31a and forming a support for the stapling unit 40 is the reciprocating armature 42 of a solenoid or coil 43, these solenoids 43 being supported in any suitable manner as by brackets extending laterally from the respective side plates SI, and said solenoids 43 being connected in circuit-relation with each other in any suitable manner, not shown.

At one side of the aforesaid plate 37, the side plates 3|, 3| support a horizontal shaft 44- to which one or more web-engaging rollers Ma are secured and carrying, at one end thereof, a worm wheel 45 with which coacts a worm gear 46 adapted to be rotated by a flexible shaft 41 operated, in turn, by a suitable electrical. motor 48.

Each of the aforesaid side plates 3| 3| may comprise an upstanding section 49 and each upstanding section comprises a slot elongated in a vertical direction in which is received a shaft 50 carrying a plurality of weighted rollers 5|.

Extending horizontally between and suitably secured to the side plates 3|, 3| is a shaft 52 which serves as a support for a web roll 53, the web W| of which corresponds in width with that of the aforesaid web W. This web WI extends over an idler roller 54 carried by one of the tie rods 32, said web W| further extending between the rollers 44a and the rollers 5|. When the web WI is thus positioned, it is disposed above the plate 3? and the edges thereof are disposed below the respective anvils 38,

In accordance with the invention, the web W, after passing beyond the above described feeding roller 2|, is disposed upon the upper side of an idler roller 55 carried by a tie rod 32, the web W thereafter being extended beneath the roller structure 35 and then being disposed flatwise on the aforesaid web W| so as to pass over the idler roller 54 and beneath. the anvils 38-, and then between the rollers Ma and rollers 5|.

Referring to Fig. 2, one of the hereinbefore described pivoted arms 33 is shown as having secured thereto a contact member coactable with an adjacent contact member 6| mounted in fixed position in any suitable manner. Secured to the movable Contact member 66 is one end of a conductor 62 which is connected with one terminal of the aforesaid electrical motor 48, the other terminal of this motor 48 having connected thereto a conductor 63 which leads to a suitable source of electrical energy, not shown. The fixed contact member 6| has connected thereto a conductor 84 which may include a variable resistance unit 65, said conductor Bil being connected to a fixed contact member 6% with which is coactable a movable contact member 67, the contact members 6S, El being suitably supported by a bracket, or equivalent, carried by the adjacent side plate 3l. The movable contact member 61 comprises a section fiia which engages with and is controlled in position by an armature 42 of one of the solenoids 43. Connected to the movable contact member 6'1 is a conductor 68 which leads to the other terminal of the aforesaid source of electrical energy.

The hereinbefore described shaft 44' has secured thereto a disk 69 carrying a lateral pin 10 coactable with a movable arm Ha carrying a contact member Connected to the contact member 1| is a conductor 12 which leads to one terminal of the above described circuit-connected solenoids 43. The other terminal of the. solenoids 43 has connected thereto a conductor 73 which leads to and is connected to the aforesaid conductor 68. Coactabl with the above described movable contact member I! is a fixed contact member it which has connected thereto a conductor l5 leading to and connected with the aforesaid conductor 63. The contact members 1|, M are suitably supported by abracket, or equivalent, carried by'the adjacent side. plate 3|.

As clearly appearsfrom the drawings, the two webs W and WI- are disposed in face-to-face relation between the rollers Ma and-the rollers 5|. As described, said rollers 5| are weighted and, therefore, bias'the adjacent web sections toward the rollers G la. Accordingly, when the shaft 44 is-rotatedi in a clockwisedir-ection, Figs. 1 and 2, it results that the webs W and Wi are moved asa unit from leit to right, Fig. 1, and. While thus moving, they pass above the plate 31 and beneath the anvils 38.

As hereinbefore described, the printer P is the pivoted arms 33 which move in a counterclockwise direction, Figs. 1 and 2 and, in so doing, close the contact member 60 upon the contact member is I. When this happens, a circuit is completed through the motor 48, this circuit extending from one terminal of the source of electrical energy by way of the conductor 63, the winding of motor 48, conductor 62, contact member 69, contact member 6|, conductor 64, contact member 66, contact member 61 and thence back to the other terminal of the source of current by way of the conductor 68, By. the described mechanical connection comprising the flexible shaft 41 and associated parts, the motor 48, when thus energized, imparts rotary movement to the shaft 44 in a clockwise direction, Fig. 1, whereby the webs W and WI are moved in a unitary manner from left to right, Fig. 1, with respect to the anvils 38.

Each time that the disk 6d of the shaft 44 rdtates through an angle of 360, degrees the pin iii thereon engages the arm Ila of themovable contact member II to thereby move the latter into engagement with the adjacent fixed contact member 74.. When these two contact members are thus closed, a circuit is completed through the solenoids 43, this circuit extending from one terminal of the source of electrical energy by way of the conductor t8, conductor 13, the solenoids d3, conductor 72, contact member 'lI, contact member 14, conductor and thence back to the other terminal of the source of electrical energy I It will be noted that the operating circuit of the motor 18 includes the contact members 66, bl and that these contact members are open when the solenoids 43 are energized, i. e., when the stapling units 49 are in their upper positions, Fig. 6. It follows, therefore, that under these conditions, the motor 48 is ineffective, except when coasting, to cause the side-by-side webs W, W I, to be moved from left to right, Fig, 1, even though the contact members 60, 6| should be closed by operation of the printer web-feeding mechanism. This is a safety feature preventing movement of the webs while the stapling operation is being effected. However, it is to be understood that the use of the arrangement comprising the contact members 66, B1 is optional. Under ordinary circumstances, the pin l0 and arm Ila are so related to each other that said pin Ill passes beyond and releases said arm I Ia immediately after the contact members I I, 14 are closed. Therefore, since the solenoids 43 are held energized for only a short interval, it follows that the use of the described safety control on the motor 48 is usually an optional matter.

In View of the foregoing, it will be understood side plate 3 I that the mechanism of my invention produces a pair of webs which are stapled together as indicated in Figs. 4 and 5. This is desirable for the reasons hereinafter noted.

A projector of the character illustrated in Fig. 1 is one wherein the projecting light beam passes through the web section in the projection field. Therefore, it follows that the web W is necessarily largely or substantially transparent. Projectors of the character thus described are usually found in brokers offices and other public places and it is customary, afer a section of the web has been fed beyond the rollers 2| and 25, to tear or cut off this web section so that the same may be suspended for visual observation. However, by reason of the transparent character of the web, it is diiiicult to read the information which has been printed thereon by the type wheel I. i

This difficulty is overcome by the use of the herein described web WI which should be more or less opaque and formed preferably from ordinary brown or white paper. This web WI, when stapled to the transparent web W, forms a non transparent backing enabling the characters on the web W to be read with ease. Sections of these attached webs may readily be hung in a convenient location and observed as desired.

Referring to the form of my invention illustrated in Fig. 8, the hereinbefore described contact members I I, I4 are shown as secured, respectively, to a support til fixed to the adjacent side plate 3i and to a movable support 8| suitably pivoted as shown at 32 to said side plate 3I. The

pivoted support 8| is biased toward contactopening position by a suitable spring 84 which is secured to the fixed support and engages said pivoted support .82. Suitably pivoted to said side plate 3 I, as at 85, is a hammer member 86 which comprises an extension 86a adapted to be engaged by the aforesaid pin ll] of the disk 69. Pivotal movement of the movable support 8| and the hammer member 85 in opposite directions, Fig. 8, may be limited, if necessary, by a suitable stop member 87 secured to and projecting from said When the pin Ill engages the extension 38a of the hammer member 86, the latter is swung in a counter-clockwise direction, Fig. 8. When said pin Hi moves beyond the extension 86a,'the hammer member 86 drops onto the movable supportfll and moves the same clockwise,

Fig. 8, whereby the contact members II, I4 are momentarily closed, the latter, in turn, closing the circuit of the solenoids 43 to thereby effect the stapling operation in the mannerdescribed.

\ This operation is repeated each time that the pin 70 engages and then releases the extension 66a.

In Fig. 9, I have illustrated a modified form of the invention wherein the respective positions of the anvil 38 and the stapling unit 49 have been reversed. Thus, in Fig. 9, the anvils 33 are disposed below the webs W, WI while the stapling units 4|] together with the respective solenoids 43 therefor are disposed above said webs. In connection with an arrangement of this character, it will be understood that each stapling unit 40 should be biased by a suitable spring, not shown, in a counter-clockwise direction, Fig. 9.

The herein described stapling units 40 may be and preferably are of conventional construction such, for example, as those such as the Markwell stapler which customarily serve for desk use in attaching a plurality of papers together by a manual operation. It is well understood that, in such a stapling unit, the staples are enclosed in the illustrated chute or hopper and that they sionto the stapling position.

Although the invention has been illustrated and described in connection with'a particular mechanism for attaching-the transparent web and its opaque backing together'by' staples; it

shallbe understood that the invention-is not to bethus-limited. Thus, stapling mechanism, when employed, may differ substantially from that therein disclosed.

It sha'll also be understood that, 'inits'broader tion is not to be thus limited. As Well, if desired, the invention may be practiced in connection with-narrow tapes or with webs wider than those disclosed. The term web in the appending claims shall be understood as covering such tapes orwebs.

While the invention has beendescribed with respect to certain particular preferred examples which give satisfactory results, it will be understood by those skilled in the art after understanding the invention, that various changes and modifications may be made without departing from-the spirit and scope of the invention and it is intended therefore in the appended claims to cover all such changes and modifications.
